To all `1li/1.0m 'it may concern Y `t Beitinownthat We, JOHN SELLRSYBN-cuor'r and Mixunrrz INDMII, citizens` of the United States, ,residing atPhiladelphia,

But the speed capacity of the machineyWaslimited by: reason of the inertia of the `parts kunder the suddenstarting and stopping action` of: the line admeasuring mechanism,resulting in ,mutilation of the transmitting'. elements as well as inprolonging the motion ofthe drum so as to cause more ,orless vibrationor dancingfin the intervals between successi-ive feed movements,wvhichgreatly,interfered with a readingof the index.

dated December 28, 19,09. yThis i new arra11gement,wliile eliminatingthe v.destructive eifectof inertia and increasing jt-hesspeed capacityof the mechanism itself, introduced a retarding elementvto composition,inathat it required the yoperator to actuate; thefspecial key oneor moretimes for eachir ylineplan ,operation consuming valuable time, tendingto dlstractrattentionfrom copy, and corre-k spondingly diminishing ftheoutput.

` -For purposes 'of illustration the invention is shown applied to thehigh speed'machine ofPatent No. '944,405 to which reference is had foradetailed description. It will sutce, for present purposes, to des-`ignate and identify some of the parts of the .and more directlyinvolvedherein, such as ypatented machinel shown in the drawings themotor cylinder 4, motor return cylinder 5, motor rack 6, and unitswheelshaft and pinion 7 constitutingelements ofthe line admeasuringmechanism; Vjustification iiidicatordruins Scoupled ith the transmissiongearingfoi' Vthe indicator actuating devices;

Aand abutment` slide 9 constituting. the connection between the lineadmeasuring niechanism and the indicator actuating devices.

.The reference numerals thus far employed i are the sameas those appliedto the corresponding parts Lof the prior patent referred* to, with theexception of 8 which in the patent designates a part of the escapenient,to-wit, the units wheel, instead of its shaft.

The justication indicator rack "of the patent referred to is replaced bya gagng member 9 having'rack teeth on the side thereofl and connectedtothe indicator drum `through multiplying gearing 10, one end of saidgagingmember being supported in a bearing 11 and the other in a cylinder12, bothformed in the supporting frame.

, .Riding within cylinder 12 is arpiston 13,

' the'inner end ofwhose rod V14 is guidedin gagingmember 9 and is heldunder elastic pressure against the arm 15 of abutment slide. 9a, saidarm extending through an elongated opening 16.

. Cylinder 12 is maintained in open communication with the air pressuresupply ythrough pipe 17, as by connecting said pipe with the chestofth'epaper feed valve mechanism 18, Fig. 1. Y s I Supported in bearings ingaging'member y9 in position to engage abutment slide 9'LL and disposedin opposition to piston rod 14 is a follower or pin 19 provided witha'slioulder 20 adapted to engage an adjustablesleeve or f :l bearing 21carried by member 9. Pin 19 extends beyond member 9 vin positiontoengagea bearing 22 on the frame.

vvThe sole purpose inmaking'the contacting elementof the-gagng `memberin the form j to wind the spring up of the adjustable follower- 19 is toprovide Ameans for setting the drum in Yproper relation to theYabutmentmember, and but for this tliecontacting point might be integralwith o r fixed upon said gaging member.

. Toiindicator drum 8 isconnected' one end Voi acm-6123, the latterpassing around directing pulleys 21 and having its opposite end attachedto a depending weight 25, the

latter serving as a motor and tending constantly to advance gagng memberSlg-towardv piston .13. 4 4 f 1n order that the motor may be caused toexert a constant and uniform pressure and be rendered more prompt vinits action, stead ofattaching-the cord directly to the weight it isattached to a bolt 26 movable in guides in the weight, a spring k27being interposed between said bolt and Weightso that the pressureexerted by the latter will be transmitted through the spring.

The spring being much quicker in action than the weight acts first inadvancing the indicator actuating devices and its powerr is rthenrenewed by the subsequent fall of the weight, in other words, the weightoperates sion after each action. Y

The pressure exerted by piston 13 on abutment slide 9@L is opposed toand exceeds that exerted by the motor 25 on gagng member 9, and so longas the motor rack 6 remains lto its original ten-k V out of engagementwith abutment slide 9a, y

said piston operates to retract the abutment slide against the pressureofmoto'r 25`until arrested by the engagement of pin 19 with bearing 22.f This position of abutment slide ,Y A 9EL with relation to the engagingshoulder on 6 enters the justification area and, in conse- 'quencethereof, moves abutment member 9a,

said abutment member remains clamped between piston rod 14 and pin 19with the latter in contact with bearing 22, owing to theV preponderanceof pressure exertedby piston 13 over that exerted .in the oppositedirection by' motor 25. When, during the advance of the motor rack, itengages and picks up the abutment slide, the latter, acting upon pistonrod 14, displaces'it by an amount equal to the measured advance movementof the motor rack as determined -bythe l escapement, therebytemporarilyI removing the previously existing obstacle to" the'ad'-,ideales vente. .of the,l indicatief actuating .devices andrespond..tortheipressilre permitting them to Q'tmotorQej ,It.willbeSeenitherefqre,that. .menib no longer-operates ,as vatransmittingme for theindicator` .actuatllsi'deitces but lather. as;alterable, stop-ifm. gagngthe .f er tent of motion gp 'rinitted .saidadmitting de#` vices, under .thenressure oflnotor; .Rires sults thatycorresponding.. mvements, of, the.
